Struct reef::Paths

pub struct Paths;

Functionality to help determine system paths

Implementations

impl Paths

pub fn home() -> PathBuf

Get the user home PathBuf

Example

use reef::Paths;
let home = Paths::home();
assert!(home.exists());

pub fn env(env_name: &str) -> Option<PathBuf>

Get a path from an environment variable

pub fn which(name: &str) -> Option<PathBuf>

uses the PATH environment variable to search for a filename matching the specified name. if a matching filename is not found, it will check for the existence of name.exe and name.bat

Example

use reef::Paths;
let git_path = Paths::which("git").unwrap();
assert!(git_path.exists());

pub fn shebang(path: &Path) -> Result<String>

extracts the text following the shebang #!

Example

given a file with the contents:

#!C:/Ruby26-x64/bin/ruby.exe

the shebang method will return C:/Ruby26-x64/bin/ruby.exe

use reef::Paths;
use std::env;
let path = std::env::temp_dir().join("test.rb");
std::fs::write(&path,b"#!C:/Ruby26-x64/bin/ruby.exe")?;
let target = Paths::shebang(&path).unwrap();
assert_eq!("C:/Ruby26-x64/bin/ruby.exe",target);

pub fn application_path<P: AsRef<Path>>(
    qualifier: &str,
    organization: &str,
    application: &str,
    rel_path: P
) -> PathBuf

get an application specific path
